Check for blown fuse(s) or blown fusible link(s).
If the battery and alternator are both good, Test them to be sure, then you need to take a multimeter and verify that the power from the alternator is actually reaching the battery. It could be a simple wiring problem
The alternator is probably over-charging the battery. Replace the alternator if the voltage at the battery terminals is over 15V when the engine is running.
If the alternator is installed incorrectly, yes, it can drain the battery.
My advice is to charge the battery with a battery charger before starting the engine. You will be putting a heavy load on the alternator if you allow it to charge a dead battery. This could damage the alternator.
could be the alternator. could be the battery, the alternator charges the battery but does not stop the battery holding a charge.could also be a bad starter motor. take alternator off and have it tested. most places will test for free
Probably loose drivebelt. or alternator belt of it is seperate.
usualy if the alternator is not defective then its the battery. you should start by cleaning the battery post. then you could check the terminal wire that runs from the battery post to the alternator. if thats not it you should check the ground on the alternator.
Possibly a bad alternator. The Alternator charges the battery when the vehicle is running. If the battery is not being charged this could cause the vehicle not to start.
If the alternator is good and the battery does not charge, then the battery may be bad. There could be problem with the electronics. You will need to take it to a place where they sell batteries. They have equipment to check out the battery and the wiring.
test the voltage on the battery first, then on the alternator. If its good then it could just be the diode in the alternator. I would suggest you replace it becuase eventually your alternator will die and the battery will not get charged leaving you stranded somewhere. It is possible to just be a battery but you wont know unless you have the battery tested. check the voltage on the battery and the alternator before you do anything else.
There is no problem...the problem was the alternator. You have fixed the problem.
the batteries only serve to start the car and the alternator. I'm not sure if it would be your alternator but it's not the battery.
